" ,VLOCOMQTIVE 3E1) nnn'strrnnsrnuorunn 2 Application filed August 13,1929; Serial 1m :asats'so.

Thisiinvention relates generally tobeds for-l ocomotivesand more particularly to beds adaptedio support a boiler of the steam and water tube type, and to" housings 7 17. therefor. v i

' Heretofo-re, the boilers usually employed in f locomotive practice have comprised a staybolted portion surrounding the fire box and the combustion chamber, and a'cylin- A10 drical barrel extending forwardly therefrom,

provided with fire tubes. 'Such boilers are adapte'd'to withstand only relatively low r gst'eam pressures; Inmy' copending applications filed on evenfdate herewith there is described a novelhigh 'pressu-re'boiler, com-' novel locomotive bed for supporting a steam") generating apparatus.

Another object of the invention is to provide locomotive superstructure" adapted to be installed 'oniior removed from a'locomotivebedfasa unit, or in sections, and comprising a smoke box, an economizer l housing, and a steamjgenerator housing.

A further object, of the 'inventionis to 1 provide superstructure of the type indicated embodying covers for-the generator and economizer which =may be conveniently "opened to facilitate installation or removal of the units.

7 Anotherobject of the invent-ionisto -pro- 7 vide a novel construction of locomotive bed,

superstructure, generator, economizer, and superheater, enabling the parts to be expedi- "tiously*assembledordisassembled. i A further object of theinvention is to provide a locomotive bed embodying detachable side frames, and an integral sauce-urembodyinge-gfbody member adapted to support 7 anges are the suba the side frames in proper spaced relation, a cylinder saddle, cylinders, distribution valve chests, a cradle, a draw bar pocket,-and pockets adaptedto support a smoke box, a steam generator, and an economizer and their housings;

1 Another objectof the invention is'to'pro-i vide alocomotive bedof the type indicated,

smokebox pockets are embodiedinan integral casting separable from the remainder of the bed. m 1

- A'further object of the invention is to provide' structures of the types indicated, which are of "great strength and durability, and which canbe economically manufacturedand maintained. 7 7

Other objects of the invention will hereinafter readily ap'pe'ari V V The improvement claimed isfhereinafter fully set forth. I V I y "In the accompanyingidrawings: Figure l is a perspective viewof a locomotive bedembodying the inventiomone of the side frames" being shown detached; Figsi 2 and-3, per-- 'spective views of a modifiedform of' con- "struction, respectively illustrating a sepiarately formed member embodying ii the pockets for'the superstructure and a'separately formed main bed memberyFig; 4, a perspe'ctive view of the superstructure with the views, respectively,"of a generator, a superheater, and an economizer of the type' adapted tobe housed and supported by the improved structure only theouter rows of tubes of the economizer and the superheater being shown; and,l31gs. 8 and 9, perspective vlews,

I y i In the practice of the invention, referring f descriptively to the; specific embodiment thereof which has beenzselected :for exemplificationv herein, two main units are employed,

' viz i a bed A and a superstructure 13'.

' The bed A preferably embodies twoydev tachable-sideframes 10, and anzintegral cast- 1 ing' comprising a body member 11 to which the: side framesv areattached, a cradle :12, V

smoke box and cylinder saddles l3, cylinders 14, distribution valve chests 15, a generator pocket 16, an economizer pocket 17, and a smoke hox pocket 18.

The body member 11 is formed with parallel vertical side walls 11*, having axle openings 1-1",-a lateral longitudinal flange 11, on each'sitle wall, and transverse verticall'ovalls 11, connecting the side walls in the nature of cross ties and spaced to form axle pockets.

Each side frame 10, is formedwit'lra top.

rail 10*, and pedestal jaws 10?, and is adapted to fit against a side wall 11 of t-hebody member snugly beneaththelatemlflan ell 15 thereof. Any suitable means such as olts, *kQyS,7I'i'V8tS,-t(i., may be employed to fasten the/side fnamestothe body'member. The ypocketili for supporting af generator :19 and its housing, is formed at its rearend witha my leg 16 united to the cradle, and its'front end is united to the body member 11. This pocket comprises an vertical front wall 1-6", vertical sidmwalls 16, and a horizontal bottommvall "16 formed with a central opening 16 for ash pan.

Thexmcket 17 for supporting an :econo- I mizer 20 and a superheater 21 and their hornsing is of tests width than thegenerator pocket Mathis iormedwithan imperforate horizontal mu bottomiwiall 17 disposed at a' higher level, :thanmhe bottom wall 1" of thegenerator pocket, and two parallel, vertical side mlls lllp The pocket 18, for supporting asmoke box 22,: is of substantiall the same width .as} the generator pocket, and is formed-with paralmide walls 22, anlta horizontal bottom wall 22 disposed at substantially the same level nethe bottom wall .16 of thegenerator pocket. v

vpmvide flanges for attaching the cover, and.

"Mgitudinally-disposedi bars .23, which 1. .providefiangesforattaching the housing to 1 the generator pocket. 'Thefront wall 23, is provided with :aeuitable opening "23 for thefpassage of the. gases of combustion.

" 'Dhesmoke boxi22, is of oblong boxshape,

l and comprises parallel vertical front and rear walls '22, 22", two parallel vertical side "waHs"22, and horizontal top and bottom 'fwltll s'22, 22". The rear wall 22", is provided with a-suitableopening 22; for the passage xii of'combustion. The economizer and ,from or installed on the! locomotive mar-sepafratus comprising atuhular fire box unit.and

superheater housing 24 comprises a main portion 24* and a detachable cover 24". The main portion comprises a bottom wall 24, two parallel vertical side walls, 24, and lon itudinal L bars 24", which provide flan es or attaching the cover. The cover 24 is ormed with anoflset portion24 to acconmwd-ate the superheater 21. Any snitablemeanssuch as bolting, riveting, welding, etc., may be employed to fasten the superstructure to the bed.

Figs. land gilhistrate a structural modification wherein the pockets for the generator, economizera'nd smoke box are formed in a separate inte ralcasting adapted to be applied to anot er separately formed into ml casting embodyinga crad1e,a body mem er,

a smoke boxsaddle, cylinders,=-anddistribution valvechests.

The improved construction provides .a locomotive bed which is of great strength, Y and durability, which can be emnomioally -IIBHll-f86tul8d:8ll(l maintained, .andlwhich is adapted to support a generator aneumomizena superheater and a smoke box,formed as --sepemte units. It iiurt-her provides 3:00 housing .which can be conveniently installed 1011 or removed from the! bed, ,and which en- ..ableseither the-generator, the eeonomizeror .thesIperheater-to be expeditiously removed -05 rate units \without dismantling the housing from the bed. Itis within the contemplation 'oftheimention to form. the generator housing, the ecmomizer housing, and. the smoke .box essepmate; units or to combinenny. two 1400 ofthemas'a nnit.

(While: theeteam'.gmeratingapparatus described a. tubular generator-and a mat-er tube-eoonomizer, it is'tobe understood .thatothe-invention is equally applicable for my;

use with boilers embodyinga tubularifire box semtion and a fire tube-section, and the term -eeomomizer as-used in the claimsis intended to be sufliciently broad .to .include, as ..an equivalent a fire tube *boiler section.

-While one of" the preferred forms of-confetmct-ionthas been shown, it: is obvious: that manyvariations-in procedure,- form, arrange- ;nrentnnd construction ofthe parts can be made, -end.the inventionds not therefore- .iimited to v the particular embodiment dis- 7 telesed, but includessuch changes andmodificationsas-come within thev spirit and scope ,of the invention: as set JfOLth in. the appended claims.
